What is true about the issuance of a 90-day certificate for a new salesperson?

The correct answer states that a 90-day certificate for a new salesperson can be issued for a limited time only. This is accurate because the 90-day certificate serves as a temporary permit that allows a new salesperson to perform certain sales functions while they complete their licensing requirements. The limited timeframe ensures that salespersons don't operate indefinitely without fully meeting the necessary qualifications and obtaining their official license.

This temporary certificate helps to maintain regulatory standards within the industry by ensuring that new salespeople are progressing toward full compliance with the licensing process. The issuance of a 90-day certificate reflects the regulatory body's commitment to ensuring that all salespersons are adequately trained and qualified to operate in the mobile home manufacturing and sales sector.

The other options, while they may contain elements of truth regarding a salesperson's limitations and activities, do not capture the essence of the issuance of the 90-day certificate in the way that the limited time aspect does. Thus, the primary function and characteristic of the 90-day certificate is its temporary nature.
